The fact that the Catholic Church claims to be “The” church is arrogance. opinion that the Catholic Church ...." is an arrogant opinion.
I'd answer some who hold it are arrogant and some hold it because they are arrogant. But it is possible to think the Mount Sinai was the mountain on which the law was given, not for any reward or becasue of any intrinsic merit but because of God's grace. In fact, I've read that one Talmudic account for the choice of Sinai was precisely BECAUSE it was NOT a very special mountain. An undistinguished and homely mountain would be less likely to distract from the splendor of the Torah.
The fact that because other Christians are not acceptable because we members won’t kowtow to the Pope is arrogance.
If this opinion is held by anyone, he does not understand Catholic teaching.
If I may make a general observation: If you come to a religion thread on a forum given to the discussion of divergent opinions, you can expect to find people who hold opinions you find arrogant. The people themselves may or may not be arrogant, and as it is not impossible that I am mistaken, so it is not impossible that you also might possibly be mistaken.
But neither of us will find out if we focus on what we take as arrogance in our disputants or the opinions they put forth, or rest our arguments on the seeming arrogance of the "facts" of those who disagree with us.
My husband says that all the time and he heard it way before we had Rush. Rush copied it from...someone. Let me see, I think it was a famous ball player but can’t remember.
